Are any of the meal plans with it? I was looking at them the other day and they all seem to either be way to much or no where near enough. I'm thinking I'll probably be eating 1 or 2 meals a day there. What's close to the law school, cheap and good?
You can get a meal plan here: http://www.campusdish.com/en-US/CSSW/So ... lPlans.htm
The campus cafeteria is >5 minute walk from the Law Quad and the food is actually pretty good and it's an all-you-can-eat setup with different food stations. At ~$10/meal, it better be. There are a good number of other restaurants (some carry-out, some sit-down) within walking distance, so it just depends on what you're looking for.
If you're going to be commuting, the Commuter Meal Plan is an option; if you're going to be on campus all the time, there are the other more pricey options you mentioned (if you're going to eat there 2x a day, it's probably worth it, and you can use it for other people if they're with you). The Flex bucks can be used anywhere, even in the cafe in Carr Collins (in the law quad) or at Hughes-Trigg Student Center where they have the Chick-fil-a and Subway, etc. (but the off-campus Chick-fil-a is closer than the on-campus one due to the location of the law quad).
List of some restaurants I frequent and all within walking distance (and there are many more within Snider Plaza) (source: personal knowledge and http://www.yelp.com/search?find_desc=Restaurants+Near+Smu&find_loc=Dallas%2C+TX#
Pizza Hut - used this many times with a small study groupSometimes Go List
Goff's Hamburgers - good burger place
Kuby's - amazing breakfast place
Dive Coastal Cuisine - a little more pricey casual sitdown place
Jack's Burger House - ol' fashioned burger house
Zoe's - have good salad/wraps, etc.Favorites
Digg's (really good tacos for ~7 bucks for a combo)
Bubba's (really good grilled chicken) - costs a little more
Peggy Sue's BBQ - great sitdown place for BBQ
All that being said, half the time, if you're on campus during the lunch hour there is some sort of organizational event that has food, so go, even if you're not a member and consider it a rebate on your student fees.
