What is the secret to finding a place that’ll give larger portions?

I pick up from places in Arlington, VA and Washington, DC. The main ones include Cava, Sweet Leaf, and Rasa, but they normally just give me items I could get there for $14 or less (like a bowl or a wrap) when I pay anywhere from $5.50 to $7.50 for these things through the app.

Are the whole foods bags for $10 worth it? I’m not really looking for breakfast or bakery items… Please help.
