Having waited table for around six years by now at Serrano's, by far the most popular little restaurant on the east side of Glacier National Park, I naturally highly recommend it. Fresh salsa daily, chips fried on a daily basis, margaritas to die for---it's a must!
This year however, we have new ownership of an old restaurant in town: the Villager. It's back and you won't recognize it! It'll be great for the area this summer with new everything: the buildings been redone, new menu---everything will be very nice.
There are also two restaurant/bars I can think of in town that are currently defunct. So, if there are any savvy restauranteurs out there thinking of this gorgeous, seasonal area: Please, come help little EG with more great places to dine in the future.
