Tried Cafe Martha for the first time using a Groupon NOW over the weekend. Quiet for Saturday lunch, there were 2-3 other tables in use. I get the impression this is more of a weekday place serving office workers nearby. Not much for atmosphere, no music or TV or other distractions. There are a few tables & chairs outdoors on the sidewalk.
We tried 2 gourmet sandwiches - Vegetarian and Cafe Heather. Both were quite good. Vegetarian is something like a caprese on a brioche roll with a nice pesto sauce. Both accompanied by pickle & a small cup of tasty homemade pasta salad for $8.50. Add $2 for drink & chips. While we both enjoyed the meal, it seemed a little pricey for the goods. I would like to see their menu expanded a bit, but I guess if they are just a lunch place, it's adequate.
The food experience was good and if I was in the area again, I would stop in and maybe try one of their salads next time.
Another plus - there is plenty of parking right outside. Nice find, especially in Old Town Scottsdale.
