When it comes to food, sometimes one serving just isn't enough. Luckily, there are plenty of synonyms for the phrase "more serving". If you're looking for second helpings, you could ask for "seconds". If you want a larger portion than what's already on your plate, you could ask for "a bigger serving" or "extra". Or, if you're simply feeling peckish and want a little bit more, you could ask for "another helping", "another plate", or "a refill". No matter what phrase you choose, just be sure to save room for dessert!
