The Purple Onion is a restaurant that is open 24 hours, and at times, it is quite crowded. They serve the typical burger menu. They get mostly the college crowd, but it is good nevertheless. I liked going there for my first time a year ago, and I have liked it ever since. I don't really hear any complaints against this restaurant. That says something because almost all restaurants of this type has lots and lots and lots of complaints. I recommend this place at four stars. Try going in off hours if you don't want it to be so crowded.
