620 Subs reminds me of La Spada's in LBTS; A small counter where the sandwich makers do their thing in full view. They call out each ingredient and you say "yes" or "no". It's a bit arduous but at least you get what you want; and you won't get something on the sub that you don't want.
They're not quite as good as the guys at LaSpada in terms of showmanship, but they get the job done. Their regular subs are BIG, the 8" sub has a pound of meat and is only $6.50, which is a very good price in Boca.
They also have a 6" sub special for lunch which includes chips and a soda. The only complaint I have is that they didn't have banana peppers. Say what? Luckily I had some at home.
This place is much better than V & S. I'm sure they hope you don't find out about it.
