I have attended San Diego Comic Con for 6 years now. It is unfortunate that it took me until last year to visit The Old Spaghetti Factory in downtown, the Gaslamp District, San Diego. But fortunate that I did visit last year. It is now on my list of must visits when I am in town.
I am always leery of places that serve gluten free pasta. How can I be sure that they will serve me the gluten free variety? When we visited last year we went with a friend who eats there regularly. He knew the answer to my question. The gluten free pasta is the only spiral pasta they serve! That means if you receive something that does not look like this, then you did not receive the gluten free version. While some may find this boring because it is the only option, I love it because it takes the anxiety out of eating here.
And this year they added the little flag too. There a quite a few options on the gluten free menu and I am thrilled that they offer marinara sauce and chicken to add. Since I can not eat beef it is nice to have a non-beef sauce and an option for a protein with my pasta.
The only think lacking here is that there is no gluten free bread. I always say I am going to bring my own but so far I have forgotten each time I have visited. Maybe next time.
Major note: Be aware (or beware) they do not claim to be a gluten free restaurant and there may be cross contamination.
I do not know if they use separate water to make the gluten free pasta, or if they change utensils for spooning out sauce, etc. I do know that I have eaten there three times and have not gotten sick or even felt off from eating there. Now recall I do not have Celiac's and I am not overly sensitive.
Also note that this is not your Italian grandma's Italian food. It is a restaurant that serves Italian food. I love it because it isn't overly spicy, it feels like a good amount of food and the price is perfect for my wallet. You get a three course meal (salad, pasta, ice cream) and a lemonade for $15 (or so, I could not find my receipt to be exact, sorry).
I think The Old Spaghetti Factory is worth a try but be cautioned again that they are not gluten free and there could be cross contamination.
