Got off the bus in front of this place every day last summer, so I gave in to temptation on a regular basis. I love the custards, and they have featured flavors that change daily. Check their website to see what's coming up. I tried many, and I liked all of them. Their hot dogs, which few people seem to know about, are really good too.
They keep winning "best of" votes/awards, so I'm surprised that there aren't more reviews. The number of people there on hot summer days tells you all you need to know about their popularity.
They have seating out front plus a drive thru, and I believe they are open year round. They sell custard by the quart(?) too,
