I used to go to Red Herring at least once/twice a week during my undergrad years.
In my opinion, the best lunch option near campus, and never as packed as some of the shittier places nearby. Soup and sandwiches were always great, and the entrees were good too. I could never convince my friends to come with me, because they were idiots.
The food definitely fluctuated in terms of taste/quality depending on who was working that day. I still remember a specific dish I had back in '05 that still ranks among the top 10 things I have ever eaten. Unfortunately, by comparison, nothing else from there ever lived up to that one dish, even though it was always excellent.
