Oh, that’s right, campus will be very busy, which means restaurants will be very busy. Expect waits at restaurants, which will be longer than usual. You can probably minimize this by eating a little earlier or later than the normal lunch/dinner times.
One place you can go which I find fascinating, and will most likely be vey quiet, is the Alabama Museum of Natural History, which is located right on campus. It wouldl be a good place to take a break and cool off.
