In C3 Districts, the Board of Standards and Appeals may permit boatels provided that the following findings are made:
(a) that such use is so located as not to impair the essential character or the future use or development of the nearby residential neighborhood; and
(b) that any restaurant permitted in connection with such use satisfies the conditions for issuance of special permits to eating or drinking places, as set forth in Section 73-24.
The Board may modify the regulations relating to signs in C3 Districts to permit a maximum total surface area of 50 square feet of non-illuminated or illuminated non-flashing signs on each of not more than three street or water frontages.
The Board may prescribe appropriate conditions or safeguards to minimize adverse effects on the character of the surrounding area, including requirements with respect to the location of illuminated signs, the shielding of floodlights or adequate screening.
