We went there lately, and they gave us a binder to look at with allergen information. The only thing with a peanut warning was the Snickers pie, which wasn't even on their current menu, thankfully.
We won't go again, though. We hated the ambiance (one big, open, bright, loud room, not any privacy, not even enough room to walk between tables) and the food wasn't very good. Applebee's is nicer than that, and we thought it was loud.
