On the Side Day Spa pampers its clients with natural products and holistic spa and nail services in a peaceful, serene environment. Masterful muscle-workers revive worn-out bodies during a one-hour mojito hot-towel massage. The experienced, licensed therapists gently stretch overtaxed muscles and joints to relieve pain in trouble spots before mummifying clients in minty-lime-scented towels. Tired, achy lower limbs can opt for a rejuvenating foot treatment and pedicure. A trained nail tech sloughs off dry skin with a brown-sugar-coconut scrub, slathers on a pineapple-papaya mask, and finishes with a coconut-pineapple massage. After a hot-towel wrap, lazy legs will be energized and ready to take on another day of work carrying their owner. Polished piggies can step out confidently in flip-flops to show off bright coats of chartreuse tangerine or vermillion pink.
