Love this place. The nachos are excellent and huge. DS and I share them, so since he does not like sour cream and guacamole, I have them on the side, which they put in small plastic containers. By the way, the guac is fantastic, chunky and tasty. We were there in April and the nachos were $7.99, and with a 10% AP discount, you can't beat it for value.
Also you can get a French Dip sandwich, which I really miss at the French Market. Since there is a soda fountain, refills are easy, and I usually take my drink back into the park.
Check it out. You won't be disappointed.
