Okay, here's what you do.
1) Find out where the Banzo food cart is hiding.
2) Order the F-Bomb. When asked about the sauce, respond confidently with "I'll take all three"
3) Enjoy.
This is one of the best food carts around. Make sure you show up early---as the lines get kinda long and the service isn't very speedy. Totally worth it! Just go now.
