I joined this forum to find some great eating spots in Nogales, AZ, but got side-tracked when I saw this thread. I live in P.A. and we have some great little eateries here.
Bushwackers - American food (eat in the bar area, the other area is really stodgy)
SoHo Bistro - Asian food - a couple blocks from the ferry
Soba Noodle - Thai food - wonderful
The Landing - adjacent to the ferry dock - great fried clams
And, if you have time, there are two wineries that are wondeful here in town - Harbingers and Camaraderie - you won't be sorry if you visit both. (I'm a retired chef still doing some catering, so I do know the food places here in town.)
Have fun - now, I have to figure out how to start a thread on here to find out about Nogales, AZ......
