I live about 2 miles away from the Ryan Center and I'm a URI grad. You have good driving directions and do allow for traffic. Actually, you have directions for the "back way" into Ryan. The rest of Rhode Island will probably take Rte 4 to Rte 1 to Rte 138 so you'll probably get there faster.
Also, on the URI campus, you can find food but it's too far to walk if you park your car first. There is also food in the Ryan Center --typical fare of hot dogs, nachos, etc. No cold spaghetti, hot potatoes or mashed bananas.
As for restaurants, drive past the entrance to the Ryan Center (stay on Rte 138) and take a right on Rte 108 and follow the signs to Wakefield (the road winds alot). There is a Chelos (very much like Applebees) on Rte 108, past Tim Hortons. If you take a left at that intersection where Tim Hortons is located, you'll find Burger King, McDonald's, Pizza Hut, Dunkin Donuts, and Taco Bell. Applebees is on Rte 1 near Holiday Inn. To get there, stay on Rte 138 until you reach the light at Tower Hill Road. Go south on Rte 1 and it's about 3 miles down the road. HOWEVER, you will NOT be able to then go North on Rte 1 if you plan to return to the Ryan Center because of the median. You will have to follow Rte 1 South and take the Wakefield exit, then and follow Rte 108 to 138. Way Too Complicated!!!
Have fun at the Wiggles!
