Here are our personal rules for dining at Ms. Martha's Caribbean Kitchen: Check the hours before you go. Make sure you have time to wait. And maybe don't visit that one week of the month when you're hanging on till the next paycheck hits. Tucked away in a North Phoenix shopping center, Ms. Martha's serves mouth-watering Caribbean fare on a limited schedule (three days a week with a fairly early closing time). We love the gently fried and impossibly flaky pates filled with beef, fish or veggies; the deep, rich flavor of the oxtails, which we like to order on a bed of rice and beans; and the pleasantly spicy jerk chicken. Nothing at Ms. Martha's comes quickly (good food rarely does) or cheaply, but none of that will matter after one bite of a perfectly spiced goat curry.
