My daughter recently moved to Placid, and I visited her last week. I had been there in the summer and had been disappointed in the food, esp the Mirror Lake Inn which you all got right as not particularly good or fun. This time I read the postings and got some very good food.
Verandah was best Cozy and warm, with exc service, the food is not very creative (altho I loved the carrots, an extraordinary thing for me to say), but beautifully executed. Also great views in daylight. I would be most happy to have this resto in Baltimore where I live. (We tried to go to Interlaken on the recs, but it was booked up.)
Lake Placid Brew Pub. Fine burgers and superb home brew. Very casual, really enjoyable.
Black Dog. Short menu, fine ingredients. Generally well done, but the chef got carried away with the sauces, which we found over-powering on the chicken and lamb dishes--tuna was exc., however. Also really good and filling potato soup.
