Pecos Bills is probably entirely new to you by now if you haven't been there in years. I don't know the exact timing but I recall it having more burger type options at some point with maybe some Tex-Mex influence and now it's almost entirely fajitas / nachos / Tex-Mex-style salads, plus still having a Southwest Burger. It's moving with the times, in a good way; can't really get that kind of food in the other parks, except for the less-Tex, more-Mex stuff in Epcot.
Skipper Canteen seems pretty reasonable for a sit-down lunch too and it's not too hard to get a reservation. Some $18-$24 options which isn't bad when a QS lunch at BoG is $15-$16.
