Grenada has several really good sit-down places to eat. However, these tend to run a bit pricy and require us to set aside an hour or two for ordering, receiving our food, eating, and getting our check. Oh, island time. I really will miss these relaxed vibes when we're gone.
But if you need to eat on the fly, basically your only good options are Subway and KFC. I think it was at the end of our 2nd term, when I was pretty fed up with cooking and doing dishes, that we realized that we could in theory eat at Subway for lunch and dinner every day of the week and not spend any more than we were spending on groceries. I guess I'll lay it out for you in case you're living in Grenada or will soon be living in Grenada, because it's nice to have a place where you can go to eat without feeling guilty about it when you NEED a break from cooking and doing dishes in an overheated, non-air conditioned kitchen.
Basically, Jared and I spend an average of $300 ec a week on groceries/eating out (that's the equivalent of around $110 US). This is fairly average for a couple living in Grenada. You could definitely eat a bit cheaper if you bought mostly local food (much of the food at the grocery store is imported and so the prices are inflated). It's also very easy to eat more expensively than this on a week-to-week basis, and we would be if it weren't for the fact that we bring loads of snacks with us from the States every time we visit home.
There are two Subways you can visit: the one on campus (gross ew flies no), and the one right by the local Excel Plaza movie theater (yes do this one always). Every day there's a new "combo of the day" (see third picture down). You can get a 6-inch sandwich combo for $13 ec, which includes chips and a drink (we always get Caribbean Cola because the rest of the local sodas are kind of weird, crazy sweet, or always "out"), or you can get a footlong combo for $21 ec. It's $18 ec if you get just the sandwich. Jared and I always split the footlong combo and that fills us both (but Jared doesn't seem to require as much food as the average man--he usually eats just a little more than I do). So if we were to do this for lunch and dinner every day, seven days a week, we would be spending exactly $294 ec on food. If we just split the sandwich and brought our own water (we do this a lot), then it would be $252 ec on food each week. That would leave us $50 ec for breakfast food and snacks (eeeeeasily done--you can get 2 dozen eggs for $20 ec at the farmer's market, plus lots of cheap fruits and vegetables).
So anyway, that's not to say that we eat at Subway for every meal. We don't. That's just to say that we don't ever feel guilty about eating at Subway if I don't have the time/will power to make a home-cooked meal. It's pretty cheap, pretty healthy, and pretty filling. We eat Subway on average once a week. Occasionally we'll switch it up with KFC, but that makes us feel grease nasty and it's a little bit more. Although Jared and I will be all-to-happy if we don't have to look a Subway sandwich in the face for the next 10 years of our lives when we're done with Grenada, we're pretty happy it's got our backs here.
