Let me just say first of all, you can get beef, steak, or chicken in this burrito - I'm not positive, but I believe steak's the most expensive, at $4.99.
The Taco Bell website says this, "The New XXL Grilled Stuft Burrito is our biggest burrito yet, STUFT full of grilled, marinated steak, a blend of three cheeses - cheddar, pepper jack and mozzarella - flavorful seasoned rice, hearty beans, reduced-fat sour cream, chunky guacamole, avocado ranch and fiesta salsa, wrapped up in a warm flour tortilla."
As I said, you don't have to get steak - I have also gotten beef, and to be honest, I think I preferred the beef. Anyways...
How's it taste? Good. There's nothing in this burrito they didn't already have at Taco Bell, but it's "Everything but the kitchen sink." To be quite honest, I really dislike the avocado ranch sauce - at least I think that's what i was tasting. Maybe it was the guacamole. Either way, there's something in there I don't particularly care for - it's one of those two things.
How big is it? (That's what she said. Er. Asked.) I think according to the website and doing a little conversion, it weighs about a pound, although it varies. I've had two of these, and the beef burrito I got felt like it weighed considerably less than the steak one I got. Then again, that can also depend on the person making it.
Is it worth it? As with the Double/Quad steak burritos, I can't recommend something from Taco Bell this expensive. It's just not worth it. Why would you spend about five bucks on one burrito, when you can get five different one dollar burritos? Sure, I'd say try this at least once, as it does taste quite good, but because of the price, I can't recommend this too much.
+ Tastes good, and is a good size.
- Expensive as a Thai hooker. Eh. Maybe a little more expensive.
