the firing range is off of Brown ave, which is one exit away from the exit to S. Willow street, aka Rt 28.
If you get back on the highway from Brown Ave and head east, your next exit takes you to S. Willow Street.
Cruise that strip and stop into any restaurant that suits your fancy.
Here's a list of what you'll encounter:
TGIFridays, Longhorn steakhouse, Bernardo's, the 99, Pizzeria Unos (Uno's Chicago Grill), Olive Garden, Ruby Tuesdays, Bertucci's, Chili's, Friendly's (NH Friendly's are disgusting, be forwarned), Taco Bell, Boston Market, D'angelos, Santa Fe Smokehouse, Yee Dynasty, Taiwan Garden, India Palace, Cactus Jacks, Pizza Hut, Wendy's, Burger King, McDonalds...
uhh that's just off the top of my head. There are many more.
that firing range is fun. I hope you enjoy yourself.
