Because you do not prepare the food you eat at restaurants, it is imperative that you ask lots of questions about the food prepation. Ask questions about what comes with the dish (fatty sauces or gravies are a red flag) and how the food is prepared (grilled, fried, etc.) Tell your server that you have acid reflux.

Instead of fried, heavy foods as side dishes or appetizers, opt for fresh, grilled or steamed vegetables.  Also, be aware of sauces, gravies and spices that may come with the veggies.  Ask your server how they are prepared and note any ingredients that may be a trigger food for you.

If it's soup you fancy, opt for one that is made from broth instead of cream, which will aggravate reflux symptoms.  Also, look out for tomato-based broths, as they also tend to aggravate heartburn.  Chicken noodle soup is a good option.

Salads are great options for people with acid reflux or occasional heartburn.  They are often filled with nutritious vegetables and fruit, most of which have a high water content and will make you feel full quickly without overstuffing your stomach.  Just be wary of high-calorie dressings and ingredients (red meat, cheese, croutons, etc.)

There's no need to deny yourself dessert when you have acid reflux.  Opt for lighter desserts, such as angel food cake with fruit or fruit sorbet.  Beware of heavy desserts, such as cheesecake, mousses and chocolate.  Finally, if you're full from dinner, skip dessert.  Try not to leave the table feeling full.
