I love Roberto's. It's perfect for any occasion. Birthdays. Anniversaries. Hangovers.
Pretty much anything on the menu is going to be delicious. My little go to is the Carne Asada Chimichanga. It runs about $7.50 but you get a huge fried burrito. Normally, they just slightly dip it in oil and it's still soft. Couple this with the fact that they slap the guacamole and the sour cream right on the thing, you end up with a wet burrito.
The expert tip is to ask for it extra crispy and with the accouterments on the side. That way, you have a crispy chimichanga and you can add the sour cream and guacamole when you are ready, instead of letting it seep into your food. As a side, it doesn't hurt to get their chips and salsa as well. It also hits the spot.
Do your best Mission Impossible impersonation to get your green / red salsa and limes without touching the sneeze guard or dipping your hands in the food. Another pro tip (from my fiancee), you get the best mix of heat and flavor if you 4 little cups of green salsa with 1 cup of red and add 4-5 limes.
