I feel that Fresh is a good restaurant whether you are vegetarian/vegan or not (full disclosure I am not!).
Overall the food is tasty and (mostly) healthy. I find my self ordering Fresh when i don't feel like preparing food at home. Personally, I find the portion sizes to be quite large and I often have difficulty finishing all my food. Typically I order one of their burgers (as a wrap - I can never finish the bun) or the squash tacos.
I have also tried a few of their juices/smoothies (radiant green, immune boost and energizer). Although the juices/smoothies are very tasty - I personally don't think that they were worth the price. The major ingredients can be found on the menu and it very easy to recreate at home if you have a decent blender. If you are absolutely dying to try one of their juices I recommend taking advantage of the weekday special were from 2:30-5:30 pm you can order a 16 oz drink (normally 8.50$) and a treat (strong recommendation for the whoopie pie) for 7.50$.
I do find Fresh a bit pricier than some of the other vegetarian restaurants I have tried, but I feel it is worth the extra $$ every now and then because their recipes are so good.
Normally I order take-out, but I have dined in a few times. Eating in house is not too bad if it isn't busy (but be warned it usually especially for brunch on weekends and dinner time). However, when it is busy the restaurant is very crowded and can feel claustrophobic. Also it is very loud when it starts to fill up - it can definitely be difficult to carry on a conversation.
Overall, I found the service to be pretty good. All the employees I have interacted with have been friendly and helpful. I will continue to order take out but will likely avoid dining in - perhaps I will have to try out the other locations.
