We were in East Glacier MT mid-September and many places were closed for the season. Serrano's is a short distance from the Circle R Motel, which is where we were staying. We walked over to the restaurant about 15 minutes before it opened for dinner and there was already a number of folks gathered, waiting for it to open. When the doors opened, the folks dashed to get in, almost in a mob-like fashion. Once we were in the restaurant, we understood why. There is limited seating - perhaps15 tables/booths. We ordered jalapeno bean dip and the special which were two buffalo tacos with chipotle sauce, rice and black beans. Service was slow, but the food was very good. When we left, about an hour later, there were quite a few people waiting for tables.
