They accept credit cards only if you spend more than $10, so keep that in mind (along with the 10% check-in discount). On a hot day, there is no place around. The only real drawback is that there is no real outdoor seating area, so you are eating you delicious custard some twenty yards from the employees' entrance of a gentleman's club.
I have a friend who has been going here for years and absolutely swears by it. My first time there proved they had truly great custard (the Western Specials with both chocolate and vanialla were great!) and awesome malts. I can't wait to try the Butter Crunch, as it looks amazing as well!
