When Bardenay or Parilla lines spill into the hall, this is where people end up
Smashburger sits airside in BOI’s Main concourse, right off the central hallway, and it’s the only national burger name that shows up consistently in airport reviews. Think standard fast-casual burger joint with airport pricing: expect around $14–$17 for a burger, fries, and drink combo, a few dollars higher than off-airport locations. It’s rated about a 3 out of 5 overall, which matches most comments: service is fine, food is fine, nothing you’ll remember tomorrow.
Hours at Smashburger tend to track the morning and evening bank of departures, roughly early-morning through early evening, but stalls can close earlier on quiet days, so don’t bank on a 9 p.m. burger before the last Delta or Alaska flight. Menu is the usual suspects: classic Smashburger-style patties, chicken, fries, and fountain drinks, plus a kids’ option that makes it an easy call for families who don’t want to roam past the main concourse. Portions run standard Smashburger size, so a single patty is fine for most people before a 2–3 hour hop.
Food quality lands in the “airport acceptable” range: several reviews mention overcooked patties or lukewarm fries during busy afternoon peaks, especially when multiple flights board in a 30–45 minute window. Seating right around the counter is limited, so at those times you may end up carrying your tray 3–4 gates down to find a table. On the plus side, multiple travelers report getting in and out in under 10–15 minutes when lines at Parilla and other local spots back up into the walkway.
What regulars do: order a basic burger and skip extra toppings to keep a combo under roughly $15, tap to pay, and stay away from custom build orders when you’re T-30 or less. If the queue hits more than 6–8 people and you’ve got time, walk toward the other Main concourse options before you commit. Tip: grab a seat first if you’re traveling with kids, then send one person to order so you’re not stuck standing with trays and backpacks.
