Go to El Pelon.

In Boston, there are two family-owned burrito "chains." One is Boca and one is Anna's. Anna's has an enormous following. Boca has its followers too, but I've never met anyone as passionate about Boca as they are about Anna's.
I, personally, dislike Anna's because I find it salty, the cheese has no taste, and the guac is not good. I'll eat Anna's, as it's passable, but I don't love it. That said, the people who love it do because of the meat in the burritos. So that's a different story. But the bean and cheese is shit, and I can't even have rice because they make it with chicken stock.
I HATE Boca. One opened in Kenmore and I was very excited. It's always nice to have another place to grab a quick lunch or dinner when I don't want to cook. And the burrito is fine--not as salty as Anna's, def too much rice (but that can be corrected if you ask for light rice), but okay. Then they decided to be assholes.
Boca has two bean burrito options for its regular burrito (which is a whole OTHER issue--they automatically make you a grande burrito, and if you ask just for a burrito--which is, oh, just LISTED ON THE MENU--they get mad cause they've already pulled out a grande tortilla): bean and cheese, or bean and rice. I used to get the bean and cheese and ask for a small spoonful of rice on it. I don't even like rice, but I eat it when I have beans because it makes a complete protein, and as I'm a vegetarian, that's important.
So the chick at the register started charging me like a dollar extra for the ounce of rice they gave me. I went in there for like a month straight, and every time, she would first charge me for a grande burrito. "No, I actually got the regular burrito." She would sigh, roll her eyes, and re-punch the numbers. EVERY. TIME. Like, dude, I come in here every day. I know you're dealing with a lot of people, but seriously? I order the same exact thing every single day. I don't want a fucking grande burrito, because THAT'S WHY THIS COUNTRY HAS AN OBESITY PROBLEM.

Anyway, then they raised the prices. So suddenly my $4 burrito that contained bean, cheese, some rice, and salsa, cost over $5. Not a huge deal, but annoying. THEN she started telling me I wasn't allowed to get the regular with bean, cheese, and rice.
The last time I went there, my burrito cost like $7.50. For a burrito that's listed as costing $4.50, that's a little ridiculous.

The thing that's really irritating is that the meat burritos are the same price, with all the same stuff as mine. That just doesn't make sense! They contain another whole ingredient! Can I just order a meat burrito and ask for rice instead of carne? Why am I getting charged the same when my burrito has one less thing?

I tried giving Boca one more chance. There's one near where I work, and I was super craving Mexican. They must have raised the prices again, because I walked out with a bean and cheese burrito, light rice, side of guac, and $1.50 change from my $10.

Also? The Kenmore register chick? She must have been spending the day in Cambridge, because there she was at the register of the Mass Ave store, waiting to roll her eyes at me. Yippee, I'd missed her so.

And for the record, El Pelon is actually the best taqueria in Boston. So tasty and their bean, cheese, AND rice burrito is a lovely $4.20.
