Teeter is MUCH better than the 2 Potomac giants I go to (Potomac village and cabin John). Both of those Giabts have abysmal produce, a difficult lay out (not intuitive), and always seem to be lacking something. Prepared and bakery items are gross/bad/tasteless.
HT (the one off of the highway and off of seven lochs) is clean, easy to navigate, has the staples plus fancy extras (I can buy diet coke and artisanal mozarelka). Prepared stuff is yummy and fruits are fresh. It may end up being more expensive, but the quality is clearly higher.
