I've lived and worked in this area for the last few years and wanted to post a few good finds.
1. Elena's Elena's Tortilleria 2441 Valwood Parkway Farmers Branch, TX 972-241-4123
Just east of I-35 on Valwood, North side of the street
Very good Mexican food, all fresh made. Very inexpensive and very good breakfast tacos. I recommend the flour tortillas for all breakfast and what they call "All Day Tacos". I am guilty of not trying much of the menu because I've never got bored of the chicken, cheese and bacon taco they call the "El Jefe". Real Coke, very good salsa. Everyone I've taken there has become a fan and addict of the place. Almost all meals are $3-5.
2. Valwood Cafe 1555 Valwood Pkwy, Carrollton, TX 75006
On the west side of I-35 closer to Luna, south side of the road.
Best hamburgers in Dallas, maybe the world. May be hard to believe but they use fresh meat, cook or a char grill, the bacon is top quality and they just have a rare way of putting a burger together. I use a lot of napkins wolfing one of these baby's down. It's a good value too as lunch only runs about $6 with fries and a drink.
3. Amici's 1022 South Broadway, Old Town Carrollton
Just south of Beltline and a block off of I-35
This is the kind of place you normally don't tell anyone about for fear you'll never be able to get a table if the word gets out. I'm a wine collector and this place is great because I can finally have a great wine with a great meal. Everything they do here they do well. Most items I've had here I can count among the best I've ever had anywhere.
An incredible experience can be had for less than $15 per person for lunches and $30-40 for dinners.
Did you think I was a fast food rube from the first two reviews? Guess again, Trotters, Spago's etc and handfuls of Michelin 2 and 3 star restaurants throughout the world.
One frustration with all of these places is they don't have good air conditioning in the summertime so I avoid them then.
I have yet to find good pizza or BBQ or bread here so I've learned to make my own. And that's how I get by in this little corner of the world.
