Well, not really, but it does help. Comfortable surroundings add to the appeal of a good meal. I had the recent pleasure of going to Firebird's Rocky Mountain Grill. It actually is the second time I've been and both were quite exceptional. It's a small chain, there's only 12 locations nationwide so far. The menu is comfort food with a sense of flair, so while chicken may be on the menu it's not likely to be served with dumplings. The atmosphere of the restaurant is such that it feels cozy yet you aren't sharing in the conversation of those at the next table.
If you do find this restaurant along your travels, I highly recommend stopping for lunch or dinner. If you leave hungry, it won't be due to a lack of good food.
