There are quite a few restaraunts on that part of US-192. We go to Outback which is in the shopping center that is at the corner of 192 and the road to Splendid China (which is closed by the way)
There are also Mc'D's, BK, Subway, Wendy's, KFC, etc, all the fast food ones and the moderate type like Outbacks.
There is the all you can eat place and right now I can't remember the name of it but it starts with an A. It is in the Holiday Inn. I never tried it but my son said it was good, all you can eat lobster for $24.
I don't know of any maps that show the restaraunts but when you get down there you can pick up little coupon books that will give you some money back from dinners, usually $2-3.
Wish I could help more, but I bet someone else will chime in too. Peggie
