I recently conducted research at a local Mexican restaurant: Tortas Sinaloa. (Tortas are Mexican sandwiches). Tortas Sinaloa is a chain restaurant in California. There are restaurants in Santa Ana, Ontario, Fontana, Corona, Baldwin Park, and Hesperia. Tortas Sinaloa not only sells tortas, they also sell smoothies/juices/shakes/aquas frescas (blended fruit drinks), and other Mexican food staples like tacos, quesadillas, burritos, etc. I was obviously researching their tortas.
I ordered the Fontana torta, which has carne asada, Panela cheese, beans, avocado, lettuce, tomato, and onion. I'll skip straight to the analysis, and tell you that my hypothesis was correct: this sandwich is really good.
I also ordered a pineapple shake while I was there. (Their pineapple, coconut, walnut shake is delicious, as well. The jig is up. I've "researched" this place before).
I conclude by stating that my research partners (my family) and I agree that Tortas Sinaloa tortas are the bomb dot com. You can quote me on that in your own research articles.
