HANOI, Vietnam — Hanoi teems with sidewalk life. Motorbikes beep as they zoom past, pushing you closer to the woman washing chickens on the sidewalk who’s crouched in front of a cafe packed with people drinking egg coffees or local beer.

It’s also a city where the crammed sidewalks will have you tripping over tiny blue chairs. The plastic seats are ubiquitous on streets where food is made on grills and carts and tops of buckets, just waiting for someone to plop down with a bowl of food from one of the myriad vendors.

For someone who would not self-describe as an adventurous eater, the prospect of street food was exhilarating and frightening. That’s why we decided to start our trip with a guided street food tour, leaving it to an expert to pick the gastrointestinal-friendly places and explain the unfamiliar options.

We opted for the Hanoi Street Food Tour (hanoistreetfoodtour.com), a well-reviewed company that runs tours in the city's buzzing Old Quarter. We chose the three-hour Hanoi Street Food Tour By Walking at a cost of $20 a person. The company also offers morning and nightlife-focused tours.

If you want the full Hanoi experience, they also sell scooter tours. But after nearly being hit by these fast-moving motorized bikes on more than one occasion, we thought it wise not to imperil others (or ourselves) with our rookie driving.

The walking tour starts at the office at 74 Hang Bac St., where you can buy tickets. We recommend swinging by in person; we easily got tickets for that day, and going there ensured we were at the right place. In Hanoi, businesses sometimes copy another business’s name, like a hotel or restaurant, and set up shop. Unsuspecting tourists can end up at the copy cat place instead of the real deal.

Standing back on a corner from the wave of scooters, our guide, Teddy, started by asking about food allergies. She checked to see if we were comfortable sharing our eats. To help us survive the manic traffic, she’d yell “sticky rice” as a cue for us to wade in together to stay out of harm’s way.

We meandered to our first stop through an alley full of hanging lingerie for sale, typical for a city where shopping is organized by blocks with similar stock.

Arriving at Bun Cha Ta, Teddy explained that most restaurants are known by numbered addresses. Many are named solely by their dish — like bun cha, a pork and noodle dish — and locals remember that dish, and where to find it. In this case, locals would describe it as the place serving bun cha at 21 Nguyen Huu Huan St., as opposed to “Bun Cha Ta.”

Climbing winding stairs, we arrived at a small room on the upper floor, where we dined on soup filled with fragrant barbecued pork. Our guide explained how to eat it — add a chile or two, but “just leave it” for flavor, don’t eat it — and detailed the broth’s mix of vinegar, honey and water.

It didn’t take long for us to appreciate the challenge of a food tour with eight stops.

One thing missing from the night’s menu? The Vietnamese rice noodle soup pho, which, in our tour guide’s opinion, isn’t the city’s main delicacy.

“Tomorrow you can have pho, but not today,” she told us.

In Vietnam, eating is a process. Small bowls accompany each meal so that diners can perfect the taste to their liking.

It’s normal, Teddy said, to spend 10 minutes fiddling with add-on ingredients to get it exactly right.

Balance is key. Diners tweak their culinary concoction to get the ideal mix of sweet and sour, salty and spicy.

Next, we made our way to a place serving papaya and beef salad. A bit different from other papaya salads in the region, this one was light on spice and big on crunch thanks to the peanuts.

Not only did we get to learn about Vietnamese food and how to eat it; we also got to see how it’s made. At the next stop, a woman preparing a steamed rice pancake called banh cuon waited patiently as our guide explained the process. Then, in front of our disbelieving eyes, she picked up a bamboo stick to effortlessly create an ethereal sheet from the batter.

Some in our group attempted the same. None succeeded.

Walking to the tiny room behind her, we sat at a table to eat the finished product, dipping it in fish sauce and vinegar with individually added garlic.

Here is where stomach-space rationing began. After just three stops, we were all stuffed. And next on the list? A plate with four different fried foods, including the sweet doughnuts that vendors sell on the street.

We diligently ate one of each. Our guide explained their provenance, along with tidbits on which people like certain foods. Her parents, for example, love crunchy fried spring rolls. But she and her friends consider that the food of an older generation.

Sensing our filling stomachs, Teddy started dishing out tips. The next place, we’d be eating crab noodle soup. The money, she said, was in the broth. Skip the noodles if need be.

For dessert we tried sticky rice and ice cream.

Flexibility was an asset for this food tour. When, for example, an American currently teaching in Bangkok mentioned how she loved black sticky rice and yogurt, our guide subbed that in. And when jackfruit came up, she asked a proprietor to slice some samples of the giant tree-borne treat.

Beer, of course, was also on tap. Our guide joked that the bia hoi, or draft beer, could be likened to water. Nonetheless, we tried some on a slim street filled with tiny tables and waiters proffering menus. Cups of beer in hand, we drank en route to our final stop for banh mi sandwiches.

We ate them with egg coffee, a local favorite. The whipped egg, Teddy explained, keeps the coffee underneath warm.

Stuffed with food, information and restaurant recommendations, I considered this a great crash course for understanding the nuances of local cuisine — one that took trial and error out of the equation. People on a food tour can typically trust they’ll be taken to stomach-friendly places. After all, happy tourists aren’t sick tourists.

That said, if you accidentally swallow a chile after the guide’s warning not to, that adventure’s on you.
