If you take the Going exit (exit 303) off I-5, you will need to go south in Interstate Ave and it will be on your right (west side of the street).
This place is delicious and I highly recommend it. They have several different BBQ sauces to choose from that are available for sampling. You get lots of quality food for a reasonable price, and it's even a little messy in a fun way. Don't go here if you are in a hurry. The atmosphere is relaxing and happy. Their Ciabatta rolls are the good ones (they are NOT tough as leather). The fried Twinkies are scrumptious (and remind me of Cafe Du Monde in New Orleans), but the fried Oreos are unbelievable!
