GPI has dining options throughout its terminal — from local institutions to reliable chains. Below is a terminal-by-terminal guide to the highlights, plus the best quick bites, sit-down spots, and what to expect on pricing before your flight.

Airport Dining · GPI
GPI operates a single terminal, so all dining is accessible once you clear security. Here are the standout options:
| Restaurant | Type | Price |
|---|---|---|
| On the Fly (Montana Coffee Traders) | Sandwiches, salads, burritos & coffee | $ |
| Goat Haunt Saloon | Full-service restaurant & bar | $$ |
| Wild Horse Cantina | Mexican | $$ |
| Flathead Mercantile & Montana Coffee Traders Express | Coffee & retail cafe | $ |
On the Fly (Montana Coffee Traders) — fast sandwiches, salads, burritos, and coffee for travelers short on time before their gate.
Quick-service counters at GPI typically get you through the line in 5–10 minutes at off-peak times, and up to 20 minutes during the morning rush. Budget an extra 15 minutes at minimum if you plan to eat before your flight — and check your Leave-By Time before you sit down so you know exactly how much runway you have.
Goat Haunt Saloon — GPI's only full-service, sit-down restaurant and bar, with craft cocktails and locally-inspired dishes.
Full-service restaurants at GPI typically require 45–75 minutes from being seated to paying the check. If you want a relaxed dining experience, plan to arrive at the airport at least 90 minutes before boarding — factor in security wait, the walk to your gate, and a buffer for the unexpected. The Leave-By calculator can fold your meal time into your total airport plan.
GPI is a small regional airport with only a handful of concessions, so pricing is simple rather than tiered — expect roughly $8–14 for quick-service items and $14–25 for a sit-down meal at Goat Haunt Saloon. Vending machines with snacks and cold drinks fill the gaps in the ticketing lobby, baggage claim, and near Gate 6 for after-hours or early-morning coverage.
Airport restaurants across the US typically charge 20–40% above street prices due to higher operating costs, rent, and logistics. At GPI, use this rough guide:
| Price Symbol | Per Person | Typical Options |
|---|---|---|
| $ | Under $12 | Fast food, coffee, grab-and-go snacks |
| $$ | $12–25 | Fast-casual, sandwiches, pub fare |
| $$$ | Over $25 | Full-service restaurants, steakhouses, seafood |
Prices as of 2026. Tip (18–20%) is additional at full-service restaurants.
Yes — TSA allows solid foods through security checkpoints at GPI. You can pack a sandwich, snacks, fruit, homemade food, or even a full restaurant meal in your carry-on bag and bring it through the checkpoint without any issue.
The restriction applies to liquids and gels over 3.4 oz (100 mL): soups, dips, nut butters in large containers, juice boxes, and similar items must follow the 3-1-1 rule or be placed in checked baggage. Solid food — including wrapped sandwiches, chips, candy, produce, and baked goods — passes through freely.
This means you can save significantly on airport food prices by packing your own meal or picking something up before you enter the terminal. See the full TSA food policy and tips in our guide: Can you bring food through airport security?
Arrive early enough for a relaxed meal
The Leave-By calculator folds your real-time GPI security wait, drive time with traffic, and gate walk into one exact time to leave home — so you arrive with time to eat, not just sprint.
