mcdonalds, has more of a selection of food. the taco bell is more of a 2 dollar combo. so its a toss up, it could get different items at mcd's or 1 main item, doritos, and a drink for 2 at taco bell.
i'd say taco bell. i always use the dollar menu at mcd's but u have to buy more to fill u up because everything is so small so u arent really saving any moneyy..
None of those choices sound very appealing, and I don't usually eat at those places. I'm inclined to think that you'd probably get more for your money at Taco Bell. At most Mexican restaurants I've been to, they really load up the plates with food.
