This is the best banh mi I've had in Arizona. Eating at Lee's pales in comparison to Mekong Sandwiches. Prices are so reasonable, they offer credit card, and the quality is so much higher.
The sandwiches hover below the $4 range, with an option to make it a combo meal which includes a drink for a 10% discount. I went with the #1 Mekong special. It included pork belly, ham, steamed pork, head cheese, and pate. It was absolutely delicious. The bread was freshly baked and had a light crisp crunch with a perfectly soft inner surface. The meats were flavorful and more plentiful than in a Lee's sandwich. I also tried the #3 grilled beef sandwich which had a flavorful marinade and was full of beef and vegetables.
Service was fast and friendly at the counter. There is a case of various Vietnamese goodies such as pate chaud and bamboo leaf wrapped sticky rice.
I also had an iced green milk tea which was overall refreshing but had a bit of a floral aftertaste which was weird to me.
So, if you're craving a sandwich you're can't go wrong with the sandwiches here.
