Next go to the restaurant in the center of the lower portion of Wall Market, as seen in the picture to the right.
Sit down and order something. Afterwards tell the waiter that the food was ‘alright’ and he’ll give you a coupon for the pharmacy. The pharmacy is just south of the restaurant. When the pharmacy salesman asks you what you want select the digestive. Take it back to the bar where the clothing storeowner was and head to the bathroom in the back. Offer the woman in there the digestive and she will reward you with Sexy Cologne.
Finally head to the south and talk to the orange guy in the white shirt. He will give you the “Member’s Card”. Go to the Honeybee Inn and use your member’s card to get inside. The two doors on the left will offer you either Lingerie or the Bikini Bottom (it doesn't matter which you choose). You now have all the items you can get.
Take this time to stock up on items and new weapons before you continue the game. When you're ready go back to the clothing store and change into your new outfit. You are now ready to make your way into the mansion.
Once you get inside and are free to wander around go up the stairs and into the open door on the left. Tifa is at the bottom of this set of stairs. Once the Don is ready head up the stairs and into the center doorway.
If the Don chooses Tifa or Aeris you will end up in a room fighting a bunch of pushovers. If Cloud is chosen, however, you’ll go straight to interrogating Don Corneo. A lengthy interrogation session ensues, with threats of testicle mutilation being the highlight. When the Don presents you with a question to which you are given three answers, it doesn’t matter which you choose. You’re going in the hole.
