Squeeze half of the lemon over the shrimp and sprinkle them with a little salt. Mix together the remaining lemon juice, tomatoes, horseradish, Worcestershire, hot sauce, celery, vodka and pepper in a small pitcher. When ready to serve, pour the sauce into martini glasses. Hook the shrimp, 4 per glass, around edges. Make garnish wedges of lemons to hook on the edges of the glasses and serve.
TIP: Chill some martini glasses in your freezer the morning of your dinner club party to serve these cocktails.
