Here is a rough cost (in US$) of typical things in Grenada, West Indies (2007)…

Bottle of local beer in the supermarket = $1
Bottle of local beer at a medium-scale restaurant = $2
1l Bottle of water = $.75–$1
1 cup of ‘fancy’ coffee (e.g. Starbucks latte style) = $? (we haven’t tried nor found a decent coffee shop yet!)

McDonald’s Combo meal = $5 (there are no McDonald’s here, but this is the rough cost of a KFC meal)
2 course meal (incl. 1 drink) at average restaurant for 2 = $40-60
Upscale restaurant 2 course meal for 2 (with 1 bottle of wine) = $100-250

Note: There are a range of options to eat cheaply, including ‘rotis’ (soft, flat bread stuffed with potatoes and curried meat or fish - very filling & delicious) which cost approx. $4 or the local ‘cookpot ladies’ as we call them, who will serve you a plate of home-cooked, local food for approx. $4. You usually get some baked chicken, fried fish or other meat, macaroni pie, fried rice or rice & peas, salad and potato salad all on one plate.

Average shopping basket for 2 people with food to last 2-3 days =
$60-80

Note: If you shop at the local market or local vendors, you can buy fresh, local foods such as fruit/veg & fish much more cost effectively and it’s ultimately more tasty & nutritious.

Average taxi ride (across city) for 2 people = $? (we’ve hired a car here as it’s much easier. Our monthly car hire comes to approx. $550 per month)
Cinema ticket for 1 = $6-12 (depending when you go)
Day
trip out of town somewhere = ? (we drive everywhere ourselves - will check out the cost of a dive/snorkel trip and update)
