The custard is very good... but I've been to some other custard stands that offer way more for less money.
The nice thing is that they do have a new flavor every single day. The downside, they have a new flavor every single day. So, if you find something you like, buy some to go as well!! They will have it again, but it never fails that it will be on a day that you can't make it!
Hint: sign up for the Flavor of the Day email and you'll know what they have before you go.
